forthereasonthatthey form no part of` skilled. inthe 'art how such connections .and

means could be constructed and arranged t0 I Assuming, them that air under pressure is admitted to opposite ends of the two pistonsrespectively, it willzbeobv-ious that one piston will return the'car to horizontal position after the load has been discharged,V the abovev enumerated stepsare just reversed and when the car reaches its normal position it is held in such position and'prevented from tilting` designated .by reference character 21. Y

It will be understood'by those skilled inV Vthe. art that the usual fastening means u sed Vwith this type of car are provided for holding the car ina normal horizontal position, it being necessary to release such holding means e prior to setting the dumping mechanism in operation Such means inthe present instance are the chains 2l.' Y

VFigure @illustrates a slight modification of the operating gear. The mechanism shown in this view is in all respects the same as that already described, except that the toothed sector extends below the .car sill. rlhe only modification rendered necessary by this change is an enlargement of the radius of the toothed sector and a reversal of the position of the bevel gear meshing therewith.

Having fully disclosed the structure and mode of operation of my invention, what l claim as new and desire to secure by Letters Patent is: i

l. A dump car comprising a body portion Vand a center sill, said sill including two spaced vertical i-beams extending throughout the longitudinal extent of the car, a series of standards bolted to said sill, a body pivotally mounted on the upper ends Aof said standards, a toothed sector fixed to said body concentric with the pivotal axisV thereof, a

`vertical shaft journaled in said sill and ex.

tending between the I-beams thereof, a bevel gear on the upper end of said shaft meshing with said toothed sector, a spur gear mountedon said shaftr and projecting 'laterally through slots in the web portions of said l-beams, a cylinder bolted to each side Vof said center sill, a piston and a piston rod operating in each cylinder, said piston rods having extensions with gear teeth formed onthe inner-sides thereof, said teeth meshin` with said spur gear,and an elon-r gated Yhousing for each of said piston rods bolted to the webs ofsaid -beams.

2. A dump car comprising a body portion and a center sill, a series of standards bolted Y to'said sill, a car body pivotally mounted on extensionsy with gear teeth formed on thel inner sides'thereof, said teeth meshing ywith said spur gear, and an elongated housing for each of said piston rods boltedto said center sill.

3. A dump car comprising a body portion pivoted to the center sillvof the car about a horizontal longitudinal axis between the body portion and center sill, a toothed sector "depending from said ybody portion in a transverseV plane at right angles to said pivotal axis and arranged concentric with said pivotal axis, a vertical shaft journaledin said center sill, a bevel gear on the upper end of said shaft meshing with said vtoothed sector, a spur gear mounted on said shaft, a pair of pistons bolted to said center sill, a piston and a piston rod operating in each cylinder, the piston rods having extensions with gear teeth formed on the inner sides thereof, said.V teeth meshing with said spur gear. Y.

l. A dump car comprising a bodyy portion pivoted to the center sill about a horizontal longitudinal axis, a toothed sector depending from said body portion in a transversevv i plane and arranged concentric with said pivotal axis, a vertical shaft journaled in the center sill, a bevel gear on said shaft mesh.

ing with said toothed sector, a spur gear mounted on said shaft, a pair ofpistons bolted to said center sill, a piston and a piston rod operating in each cylinderthe piston rods having extensions with gear teeth formed on the inner sides thereof, said teeth meshing with said spur gear. e

5. A dump car comprising a body portion pivoted tothe center sill about a longitudinal axis, a toothed sector depending fromV said body portion in a transverse vplane and arranged concentric with said pivotal axis, a vertical shaft journaled on the center sill, a bevel gear on said shaft meshing with said toothed sector, and fluid pressure actuated means disposed parallel with said longitudinal axis for rotating said shaft Vin either direction.

6. A dump car of the kind described, comprising body portion pivoted to the center sill about a longitudinal axis, a gearsector depending` from said body portion in a transverse plane and arranged concentric vwith said pivotal axis, an antifrictionlateral' guide bearing for said sector; a longitudinally disposed cylinder fixed tothe center sill and adapted to have fluid pressure admitted to and exhausted from the ends thereof, a'piston and a piston rod operating in said cylinder and gear connections between said piston rod and said gear sector.
